A version of https://archive.org/details/HowGodMakesGod that runs faster due to being emulated on a Macintosh II (with 68020 processor) rather than a Macintosh Plus (with 68000 processor).
Start with the About option, then choose the Beginning option. During a chapter (aka 'thread'), clicking the ? button will bring up an explanation of the currently visible control bar (of which there are two - start-of-chapter and mid-chapter), and clicking the S button will bring up the speed-adjustment window. The advice on the above-linked page about ideal speed settings does not apply to this version due to the faster emulated CPU.
Information about the program's history is available via the above link.
